Abstract


It was evaluated the Schirmer Tear Test 1 (STT-1) in 100 dogs randomly attended in order to identify its variations and possible relations with the clinical review, disease, breed, age and sex. The STT-1 was accomplished in both eyes in dogs over two years old, females or males. Of these, those whose complaint included ocular clinical signs or those with previously identified ocular disease were excluded from this study. After analysis it were computed 92 dogs (194 eyes), 34 males and 58 females with 7,79 ± 3,7 e 7,76 ± 3,7 years old, respectively. About the breeds, 40,2% were mixed breed, 13,0% Poodle, 6,5% Shih-tzu and Basset Hound and 5,4% Pitbull. STT-1 <10mm/min was observed bilaterally in 4,3% of the dogs with mean age 7,4 ± 3,9 years old. Of these, 75% females and 25% males. STT-1 ≥ 10 e ≤ 14 mm/min was observed in 3,2% of the dogs, of these, 66,7% males and 33,3% females, 66,7% mixed breed and 33,3% Teckel. The mean age was 7,6 ± 3,8 years old. About the systemic diseases observed in the animals with STT-1 <10mm/min it were found reproductive apparatus changes(42,8%). It is emphasized the STT-1 in the clinical-surgical veterinary attendance even when the main complaint does not relate the ocular system, mainly in patients over seven years old.
